Polyarylene sulfide resin composition

Abstract

A poly(arylene sulfide) resin composition comprising a poly(arylene sulfide) and, as a modifier, an organic amide compound compounded in a proportion of 0.2 to 10 parts by weight per 100 parts by weight of the poly(arylene sulfide).

What is claimed is:  
     
       1. A process for producing a poly(arylene sulfide) resin composition comprising a step of mixing 
       (a) a purified poly(arylene sulfide) obtained by removing a polar solvent, oligomers, unreacted monomers, by-product and impurities after polymerization, and  
       (b) at least one organic amide compound, as a modifier, selected from the group consisting of N,N-dimethylformamide, N,N-dimethylacetamide, N-alkylpyrrolidones, N-cycloalkyl-pyrrolidones, N-alkylcaprolactams, N-cycloalkyl-caprolactams, caprolactams, N,N-dialkylimidazolidinones, tetraalkylureas and hexaalkylphosphoric triamides in a proportion of 0.2 to 10 parts by weight per 100 parts by weight of the purified poly(arylene sulfide).  
     
     
       2. The process according to  claim 1 , wherein the step of mixing further comprising of mixing 
       (c) a filler in a proportion of 0 to 800 parts by weight per 100 parts by weight of the poly(arylene sulfide).  
     
     
       3. The process according to  claim 1 , wherein the organic amide compound is at least one compound selected from the group consisting of N-alkyl-pyrrolidones, N-cycloalkylpyrrolidones, N-alkyl-caprolactams, N-cycloalkylcaprolactams, caprolactams and N,N-dialkylimidazolidinones. 
     
     
       4. The process according to  claim 1 , wherein the N-alkyl-pyrrolidone is N-methyl-2-pyrrolidone. 
     
     
       5. The process according to  claim 1 , wherein the caprolactam is ε-caprolactam. 
     
     
       6. The process according to  claim 1 , wherein the N,N-dialkylimidazolidinone is 1,3-dimethyl-2-imidazolidinone. 
     
     
       7. The process according to  claim 1 , wherein the poly(arylene sulfide) is poly(phenylene sulfide).
